Application filed March 5` 1925. Serial No. 13,329.

`lTo ZZ 'whomrz't ,may concern: l Y i Y Y Be it known that we, GEORGE A. Woon andrGnoi-:Gn E. VVoomcitizens of the United States, and residents of Southington, inthe 6 county of Hartford, State of Connecticut,V

have invented certain `new and useful Improvements in Processes of Making I-Iand Tools, of ywhich the following is a specica- This invention relates to the manufacture of hand ,tools ofthe' type provided with a handle through which extends a shank hav-v ing ou one end a head and on the other end a bolster with aferrulevin which one end of l5 the handle fits. In theA present illustrative disclosure, wek have shown, by way of exempliiication, a chisel manufactured inaccord v ance withthe present invention, butv it is to bek understood that `our improved method may be `employed for manufacturing tools other than chisels, as, for example, screw drivers. n f y y y In accordance with the present invention,

, we provide an improved method Yfor manu- 25 facturing ltools of this sort, the method he ing Vsuch that it may be easily and economi-v` cally carried `out and result in a hand tool characterized by its extreme strength and durability. More` particularly, the shank, which extends throughthe bore of thehan- (lle, is formed of two parts orv stems, eneof l which is constructed integrally with the head and the other of Vwhich isconstructed integrally with thebolster, and-these stems are unitedior welded together within the boreof the handle. cordance with ,the present invention, Athe metal portion of the tool, although initially `formed of more'thanvone part, constitutes an integral whole; the head may he of substantial: size yand entirely cover the outer end of thc-.handle so as to protect the same against being "struck they handle yis rigidly securedhin place and protected in Asuch inanor cracking is reduced to a minimum;v and the joint between kthe stems which constitute the shankis yconcealed from view by the handle and the necessity of finishing or polishing this joint is eliminated. In the accompanying: "drawing, we have shown, for illustrative purposes, a hand tool which may be constructed by proceeding in accordancey with the present invention.

f head e.

By proceeding inv ac-r ner that the likelihood of the same splitting Fig. 2 is a side view of the metal parts of the hand tool before these parts are united.

-.Referring ,to the drawing in detail," and particularly to Fig. l, a denotes the operative portion of the hand tool, andV which portion is here shown, for illustrative purposes, as being in the form of a chisel, al-v though, as stated, it may be shaped to constitute a screw driver or other appropriate tool; b is a bolster portion which may be formed integrally with, or permanently united to, the blade a; and c indicates a handle which may loe-formed of wood or other suitable material and Yone end of which is vtapered and locatedV within the socket formed bythe ferrule on the bolster. Ex-y l tending centrally through thehandle is a shank d having on its outer end an enlarged stems 10,` and 11 welded together, as at l2 'and as hereinafter described more Vin detail; l

onev of the stems l() being formed integrally with the lbolster and the other stem ll integrally with the head e. In accordance with sour method, the handle C isformed with a central longitudinal bore 15 which, if de sired, may be of increased diameter -for a portionof its length, as indicated by the nu,- ineral .15.f The bolster. b u'and the blade a may, if desired, be formed from a single Between the head and the outer end piece of stock. Formed integrally with the bolster is a tapering ferrule I6 and the stein 10 which extends axially up Athrough the ferrule. This stein, preferably, is cfa diameter to closely fit in the Vlower end of the axial bore 15 of thek handle so that the han# dle will have a substantial bearing on this stem.`

The knob or head e and the stem l1 maybe formed by taking a round piece of stock of suitable length and diameter and swedging thev same into the desired shape and' length, as shown in Fig. 2. In the present instance the head is of substantial diameter so that it entirely Covers the outer end of the handle and thus protects the same; The stem 11, in the present instance, is made of two diameters, vthe lower end being substantially or' the same diameter a-s the stem 10 and the upper portion 11 being of a somewhat larger diameter and tting closely in the enlarged portion 15 of the bore so that the upper end of the handle Vwill have a sub'- stantial bearing on this portion 11.

After the metal parts are' suitably formed, the-,leather washer may be slipped into place on the stemll, and this stem then' inserted into the handle. The stem l() is then inserted into the lower end ot' the borejof the handle and brought into engagement with the lower end of the stem 11. The stems are then welded together, as by ypassing an electric current through the parts while urging the parts towards one another. It will be noted that the bo-re of the handle about the welded joint 12 is larger thany the diameters of the adjacent ends or' the stems 10 and 11, this arrangement being provided in order to allow for' the swell or flash formed at vthe joint by the welding operation and to permit of an air pocket or space between the weld and the handle and thus prevent burning of the latter.

By preference', the bolster b, the blade a, the stem 10, and the errule 16 may be constructed by proceeding in accordance with the method disclosed in U. S. Patent No.

1,139.392, granted May 11, 1915, to George socket, may be formed in the bolsterV about the'fbase ofthe stem in order to provide a' socket of increased depth. The stem 10 may Vthen be inserted int'o'the handle and welded y.to the stem 11 of the head, as previously described.

`It will be noted that, by proceeding in acccrdance with the present invention, the metal portion of the handle constitutes an integral unit characterized by its strength and durability from one end oi the tool to the other. The parts may be economically manufacturedr and assembled at a relatively low cost. y l

lIt' is, of course, obvious that my invention is susceptible of various modifications which are within the spirit of the invention without departing from the scope of the following claims, it being understood that the present disclosure is by way of illustration only and it is not to ber taken as restrictive of our conception. A

lVe cla-im as our invention: Y v

1. The process of making a hand tool, which consists iny forming a handle with a bore; forming a bolster having at one end an integral :te'rrul'e 'and a stem; forming a head having a stem; inserting said stems into the opposite ends oit' said bore; and" welding the abutting ends of said stems together between the ends oit and within said handle. e

2. The process of making a hand tool, which consists in forming a handle having a bore; forming a bolster with an integral erruleat one end and with a stem extending through the socket of said errule; forminga head with a stem by swedging a ieee of stock to thedesired shape and size;

inserting the stem of saidv head inthe outer end of the bore of said handle; slipping said handle over said irst mentioned stem and into said socket; and passing an electric current through said stems to form an electric weld between their adjacent ends and within and between the endsof said bore ol" said handle.

3. The process of making a hand tool,-

which consists in forming' a. handle with a through bore; forming a bolster having at one end an integral ferrule and a stein extending aXially through said Jferrule; forming an enlarged head with a stem; inserting said stems into the opposite ends of said bore and bringing them into abutting relation; said stems and bore being formed to provide a space between the wall of the bore and the abutting ends of said stems; and forming between theends of said handle a weld between said stems by passing an elec'- tric current therethrough.

4. The process of making a. hand tool; which consists in forming a handlev witha through bore one end of which is of larger diameter than the other end; Jforminga7 bolster'v with an integral ferrule and a stem extending through said ferrule': forming a head with a stem having an end portion of substantially the same diameter `as the rst stem and a portion adjacent saidr head ot substantially the same diameter as the cnlarged portion of the bore in the handle: inserting the stems in therespectiveI ends ot the bore of said handle; and'welding said stems together between the ends of and within said handle by passing a current therethrough.
